Note: Many of these models do not have an IAT (Intake Air Temperature) sensor from the factory. On these cars, we strongly recommend installing a GM IAT to allow for air temperature correction. What you get in the box:

Note: Although there is a paid upgrade to TunerStudio, it is not needed to tune this ECU. The free version included on the USB Stick can access all the features and tables of the MegaSquirtPNP. The paid version of TunerStudio simply adds tuning and analysis software, such as VE Analyzer Live to tune the fuel tables based on wideband O2 feedback (requiring a wideband O2 sensor and controller, sold separately).

Best bang for the buck! As you already know, MS is great. The ease of install with the PnP is awesome. I currently have the DIY Trigger Wheel and LS2 coils setup. I have configured my e-Fan to work with the ecu as well. No separate fan controller needed which saves money or the money you were going to spend on the unit, put it towards the EMS. With Boost control available, MS can control just about everything. It is great to be able to open your laptop and control a majority of components in one program rather than having piggybacks with separate controllers. The list goes on and on and so far, I have not used all of the features. To top it off, DIY's customer service is great! Always there to help and courteous. Keep it up DIY!

The only other potential must-have is that if your laptop doesn't have a 9 pin serial port, you will need our USB to serial adapter to connect to this unit. However, there are several other things you may wish to add to use this unit to its full potential.

Our bolt in trigger wheel kit will allow using sequential injection or distributorless ignition conversions. Single cam KA24E motors typically require a 54 mm trigger wheel, while twin cam KA24DE motors usually require a 50 mm trigger wheel. This MSPNP fits a wide variety of applications and Nissan built many variants of this engine, so please measure the wheel in your distributor before ordering a trigger wheel.

Questions & Answers

Yes, although on some applications you may need one of the outputs for fans or the like, so some installs will need to run the coils in pairs instead of fully sequentially. You will need our drop in trigger disc - please check if you need the 50 mm trigger disc or 54 mm trigger disc before ordering.

If your coils don't have built in ignition modules, this is not a problem - just add our QuadSpark ignition module. The only "gotcha" are motorcycle CDI pencil coils, which have very low spark energy if you try using a conventional ignition module. I've seen these used in a few poorly thought out coil on plug "conversion kits". If you really want to run a set of motorcycle CDI coils, you could use an M&W multi channel CDI box.
